How to Complete a Claim–Evidence–Reasoning (CER) Diagram | Science Literacy Lesson

$5.50

Differentiated Practice with Scientific Explanations and Evidence.

This lesson builds student proficiency with the Claim–Evidence–Reasoning (CER) framework through structured practice, reading support tools, and differentiated task options. Students learn to distinguish claims, evidence, and reasoning and then apply those distinctions to increasingly complex scientific texts.

Students begin in a digital classroom space that includes optional reading supports such as translation tools, simplified vocabulary, text-to-speech, and a science dictionary. These tools are available to reduce language barriers while keeping the cognitive task focused on scientific reasoning.

Students then:

  • study the components of CER and how each functions in an argument

  • practice matching claims, evidence, and reasoning using short experimental scenarios

  • complete differentiated CER tables

  • select an article at an appropriate difficulty level

  • write a concise summary of the article

  • construct a full CER diagram based on the article’s content

  • identify and define key scientific vocabulary from the text

Across all pathways, students are expected to:

  • distinguish observation from explanation

  • select appropriate evidence to support a claim

  • explain how evidence justifies that claim

The lesson is designed to support:

  • explicit instruction in scientific argumentation

  • gradual release from guided practice to independent CER construction

  • differentiation without changing learning goals

  • integration of literacy skills within science content

It functions well as:

  • an introductory CER lesson

  • a scaffolded practice activity

  • or a reinforcement lesson within a science literacy or inquiry sequence
